Singapore's NEWater reused wastewater passes latest testThe PUB utility reported on 2 July 2009 that the seven-member panel, which meets twice yearly, found NEWater to exceed Singapore national, US Environmental Protection Agency and World Health Organization standards for drinking water. The comprehensive sampling and monitoring programme was established in 1999 as part of the research and development for NEWater and has been gradually expanded from 190 physical, chemical and microbiological parameters to more than 290 monitored today. Chair of the panel is Professor Joan Rose, Homer Nowlin Chair in Water Research, Department of Fisheries & Wildlife, Michigan State University, USA, Said Prof Rose, "We are very pleased to note that the high quality of NEWater has remained consistent all these years. In tandem with the rapidly evolving water R&D sector, the audit process has become more rigorous over the years. Even with additional parameters to be monitored and lower levels of detection through more sensitive instrumentation, NEWater still goes beyond the mark in all measures of quality. This demonstrates that the quality of NEWater surpasses international standards, and it also stands up well against the criteria established in Singapore." Introduced in 2003, NEWater is high-grade reclaimed water produced using advanced membrane technologies. Four NEWater plants currently meet more than 15% of Singapore's total daily water needs. The latest and largest facility to date, with a capacity of 50 MIGD (227,300 m³/d), is being built on top of the Changi Water Reclamation Plant. With the combined capacities of the five plants, NEWater can meet 30% of Singapore's daily water needs by 2010. NEWater is mixed with raw water in reservoirs before undergoing further treatment at the waterworks for supply as drinking water. The existing plan is to progressively increase the amount of NEWater in reservoirs beyond current limits. Posted on 03 July 2009
